ddi 222The digital diaphragm dosing pump for difficult liquids

�

DDI ���

the Highlights

• Easy input and display of the dosing rate in l/h or gal/h with perfect calibration for optimum operating convenience and unparallelled levels of precision

• Smooth, nearly continuous dosing ensures a high process quality and optimal mixing of liquids

• For especially viscous liquids, there are � Slow Mode steps and special valve combinations

• Hotkey for easy query of the dosed quantity allowing optimal control of the consumption of chemicals

• Low energy costs thanks to the EC motor technology with maximum ef-ficiency

• Pump excess pressure control by digital input of the maximum backpres-sure allowed before the pump stops

• High process reliability thanks to the double diaphragm system

• Radical reduction in variants and spare parts: 1 motor, 1 gearing and � dosing head sizes fit the complete pump series

• Adjustment range 1:800

• Various possibilities for individual customer applications, e.g. contact or analogue signal control, batch or timer dosing

• Analogue and digital interfaces without extra charge

double diaphragm system with diaphragm control for protection of the pump in case of diaphragm leakage

Standard: ddi model 222 with double diaphragm technology

• If there is a working diaphragm defect, the pump contin-ues to dose with the robust protective diaphragm.

option: with diaphragm control

• For applications where the process must not be inter-rupted in the event of a diaphragm leakage, a differential pressure sensor is optionally available.

• In the event of a working diaphragm leakage, the sensor immediately sends out a signal, while the pump continues to dose with the protective diaphragm.
